Patent CA-2239322-A1 (CA)
Inventor: PETRISKO JOHN DENNIS
IPC: H01R25/16
Filed: 1998-05-29
Abstract: An electrical busway plug-in brick for mounting on a busway housing includes openings which allow access to bus bars running along the length of thehousing. Barrier members are preferably positioned across the openings to restrict access of fingers or other similarly sized objects through the openings, while allowing electrical contacts to be made therethrough. The plug-in brick preferably includes a lockable cover which deters unauthorized access to the openings of the plug-in brick. The openings may extend unequal distances through the plug-in brick in order to provide increased creep and strike distance which prevents electrical arcing. The plug-in brick may be mounted on the busway housing by release pockets which prevent destruction of the plug-in brick upon a short circuit by allowing the plug-in brick to be detached from the housing.

Abstract: Apparatus and method for testing an open-hole well and obtaining a fluid sample therefrom.  The apparatus comprises a compression packer on a drill pipe.  Disposed in the drill pipe is a housing, defining a surge chamber therein, and a closure valve in communication with the surge chamber.   A fluid sampler is in communication with the surge chamber.          In operation,  the packer is placed in a set position by setting down weight.  The closure valve is pressure actuated so that fluid is flowed from a formation or zone of interest into the  surge  chamber and  then  into  the  sampler.   By opening  a  housing valve  at  an  upper  end  of  the  surge chamber,  formation  fluid  may  be  forced  back  into  the formation or zone of interest by a bull-heading operation.        In a preferred embodiment,  the packer and drill pipe are disconnectable from the remainder of the apparatus, and the packer is drillable.

Inventor: HELMS ROGER WILLIAM
IPC: H01H77/10
Filed: 1998-09-17
Abstract: A molded case circuit breaker has a moving conductor assembly which includes a modular carrier assembly incorporating a plurality of spring biased contact cam members each of which engages contact pressure lobes on a pair of contact arm laminations to provide contact pressure. In response to the magnetic repulsion forces generated by a short circuit, the springs compress allowing the cam members to pivot and side step the contact pressure lobes so that the contact arm blows-open with little resistance. The cam members and springs are preassembled in a transverse channelin the carrier body and laterally retained in place by side plates for easier pivotal attachment of the contact arm laminations to the lobes on the side plates. The side plate lobes raise the contact arm relative to the mass of the carrier to reduce eddy current heating and provide a positive off indication for welded contacts by restricting movement of lower toggle links of the operating mechanism which are coplanar with the side plates. A modular crossbar includes molded bearings engaged by or made integral with hexagonal metal shaft sections which extend into hex openings in the carrier bodies of adjacent poles.

Patent CA-2252178-A1 (CA)
Inventor: PIERSON NOWAL
IPC: F16D9/06
Filed: 1998-10-29
Abstract: An improved drive shaft connecting device, including a novel shear bolt for connecting two ends or flanges of the drive shaft connecting device in a manner whereby the separate parts of the drive shaft connecting device are securely connected to each other and are yet free to disconnect from each other and rotate relative to each other in the case of an overload condition on the drive shaft or drive shaft connecting device. The shear bolt is double ended (i.e. threaded on both ends) and shouldered on both ends. The threads on each end allow the two flanges of the drive shaft coupling device to be pulled together to a pre-determined distance, which, together with a shear point, is set by the distance between the opposing shoulders on either side of the shear bolt. As well, the flanges of the drive shaft coupling device are designed to accept the shear bolts in slotted openings. The shear bolts are designed so that there is a flat area on the shear bolt where it fits into the slots of the drive shaft coupling device, so that the resulting fit of the shear bolt into the drive shaft coupling device prevents the shear bolt from rotating within the slot of the drive shaft coupling device. By preventing the shear bolts from rotating, this fitting arrangement allows for easy installation and removal of threaded nuts on the shear bolt.

Title: Method and apparatus for automated design of complex structures using genetic programming
Inventor: KOZA JOHN R
IPC: G06F17/50
Filed: 1997-02-20
Abstract: An automated design process and apparatus for use in designing complex structures, such as circuits, to satisfy prespecified design goals (10081016), using genetic operations (1046). The present invention uses a population of entities (1022) which may be evolved to generate structures (1024-1028) that may potentially satisfy the design goals (1008-1016). The behavior of such generated structure is evaluated (1008) in view of the design goals, and those structures more closely meeting the design goals are evolved further (1020-1044) until a structure is generated that either meets the prespecified design goal (1010-1016) or some other process completion criteria (1046). In this manner, a design complex structure may be obtained.

Title: Multi-access communication system and uplink band allocating method
Inventor: MATSUNAGA YASUHIKO
IPC: H04N7/173
Filed: 1999-01-15
Abstract: In a multi-access communication system where a center station dynamically allocates the band of an uplink to subscriber stations, the band of an uplink is flexibly and efficiently allocated when the up-service quality is insured. When requesting a service quality assurance, the subscriber station 30 transmits the service quality request information 210 to the center station 10. The center station 10 transmits the identifier allocation information 310 to the subscriber station 30 to allocate an identifier. When the service priority is high, the center station 10 periodically transmits the reservation transmission permission information 410 and 411 to the subscriber station 3 at the reservation permission transmission intervals 910, thus checking for the presence or absence of reservation information. Waste consumption of the up-band can be suppressed by periodically transmitting the reservation transmission permission information even if subscriber stations issue up-data at irregular intervals. The upper limit value of up-delay amount can be insured by adjusting the transmission period of reservation transmission permission information.

Abstract: The present invention significantly improves the signal to noise ratio (SNR) in a passive optical array comprising sensors (110) located in rungs between a distribution bus (100) and a return bus (120).  Erbium-doped optical fiber amplifiers (130, 132) are included in the buses proximate to each rung coupling to offset the coupler splitting losses. The gains of the amplifiers are selected to offset losses due to the couplings. The overall SNR can be maintained without significant degradation even for large numbers of sensors. In one aspect of the present invention, the amplifiers are located along the distribution and return buses directly after the couplers (140, 142), except for the last coupler. In a second aspect, the amplifiers are located directly before each coupler. The optical amplifiers preferably are made of short lengths of erbium-doped fiber spliced into the distribution and return buses.
